Baoding LED street price | Baoding LED lights manufacturers | Baoding LED lights our road lamps, basically using HID lamps and magnetic ballasts increase with the trigger mode, although the existence of this model of energy efficiency is low and strobe problems. The electronic drive circuit LED lamps, outdoor lighting occasions when the threat of an important aspect of it is the lightning induced plasticity problem. As we all know, lightning in the air is a broad spectrum of emitted radio waves, road lamps and overhead power lines, it is well accepted wireless. Two power line receives radio waves emitted by the same lightning, in terms of the driving circuit is part of the common-mode interference signals, common-mode interference Bai ground up to several volts to several thousand volts, it is easy to drive within the circuit breakdown EMC grounding capacitor or a smaller ground (for housing) clearances, resulting in damage to the drive circuit. In addition, as China's power line is a three-phase four-wire grounded neutral polarity power supply, so the overhead power lines in two paragraphs, sensing the moment the lightning radio waves, since the two power supply lines to ground instantaneous impedance between two different power lines leaving produce a differential mode interference voltage, the transient differential mode interference voltage can also be reached hundreds of volts to 3000 volts, the voltage tends to breakdown the driver circuit power rectifier diode and India CLEARANCE different polarity electrode system between the circuit board, LED Controller will also make driving circuit damage. To solve this problem, you must input of the LED driver circuit, and then varistor rapid response in order to ensure discharge differential mode interference. Due to lightning induced interference is repeated several times, when the interference voltage is high, the varistor transient conduction discharge current may be large, so varistor used not only should have rapid response capability, it should also have instantaneous guide through tens of ampere discharge capacity without damage. In addition to using varistors, the input of the LED driver circuit should be combined with conducted interference (EMI) protection, the design of complex LC network, so that these LC networks can not only hinder the internal leakage EMI on the grid, but also to interference signal lightning play a significant extent. Baoding LED street light LED street lamps technical requirements parameters: LED lights using high quality aluminum alloy materials, light surface do spray, the surface should be able to withstand mechanical pressure and salt spray, car exhaust, and corrosive cleaning agents and the like. LED lights shell protection grade: IP65 or higher. Good bat wing light distribution design, reflective optical system using three-dimensional light guide or lens design, the lens shall be non-imaging secondary optical lens to ensure that the surface brightness and uniformity, to increase the range of radiation. LED lamps must be inspected Guangdong Province LED street light product evaluation benchmark system to detect bodies and to provide inspection reports (LED lamps shall bidders in this tender with LED product belongs to manufacturers of products) LED lights ambient temperature should be able to meet -20 ℃ ~ + 50 ℃, suitable for use in Guangdong Province. At the same time should meet the specific use to the ambient temperature, humidity and corrosion and other special requirements. LED lamp power factor: ≥0.95, lighting drive power efficiency of 90%. LED lights work AC voltage range: 85V ~ 265V (LED lamps still work in this voltage range) LED lights have surge suppression performance (anti-lightning), the input over-voltage protection, when the voltage returns to normal to resume work. LED street lamps after midnight must have the function of automatically adjusting the lamp power. Lamps need to have the elevation angle adjustment functions to ensure road illumination effect to achieve the largest area.
